The trailer reveals Tom's character Alfie Solomons will be in the new series. He is seen in a quarry, holding a dog.

However, things don't look too good for Polly (Helen McCrory), who is seen being led up to a noose.

What happened in the last series?

The final scene of series three saw the Shelby family herded into a fleet of police cars, whilst Tommy looked on cool, calm and collected. It was a dramatic end to what had been a series full of twists and turns.

In the final episode, Tommy raced against time to save his kidnapped son Charlie, before he summoned his family and dashed money across the table to each of them, reminding everyone that if they took “the King’s shilling” then they had agreed to kill.

Before the police burst into his countryside mansion, the mobster explained to his family that they were all going to be arrested, but that he'd managed to strike a deal . . .

Alfie Solomons is last seen staring down the barrel of Tommy's gun, after the Brummie gangster discovers that the London gang leader is the leak and was responsible for the kidnapping of Charlie.

It followed a dramatic series that involved guilt, redemption and a dangerous Russian princess.

The show's writer, Steven Knight has revealed that he wants the Shelby crew to reach the 1920s period and cover the fallout of the General Strike in 1926.

At this time in history, a huge number of employees across different industries, joined forces to support the coal miners - who had been locked out of their mines after a dispute with the owners who wanted them to work longer hours.

Steven has said he believes the time was a true "between the wars" story, as Birmingham recovered from WWI with no knowledge of the impending WWII.

The writer said: "I hope it does run and run all the way up to the Second World War, but it does get harder to get the cast together as the actors are being pulled into feature films. It’s a victim of its own success."

Are there any new faces in the cast?

Oscar-winner Adrian Brody was spotted filming scenes in Liverpool earlier this year. Show bosses are keeping tight-lipped about his role but some fan sites are suggesting that he will play a new villain called Luca Changretta.

Adrian won an Oscar for his role in Roman Polanski's acclaimed film The Pianist, where he portrays a Polish Jewish musician struggling to survive the destruction of the Warsaw ghetto in WWII.
